Tent of Horrors

In Chrono Trigger, there is a tent in which Crono can enter known as Norstein Bekkler's Lab. With 40 silver points, Crono can participate in a game of Simon Says. The prize for winning this game is a doll that looks like the character who completed the challenge.

SPOILER ALERT!

Later on after Crono dies, it is revealed that he can be brought back to life if one climbs Death Peak with the Chrono Trigger(item) and a copy of the one they want to bring back. This is where the 40 point game truly comes into play. Whether the player has already won the doll with Crono or wins it with another character whom then requests a doll that looks like Crono, it gets sent to his house where the team retrieves it to use on Death Peak and revive Crono.
